Sweet job Rodot!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
So I just wired it up like the schematics and boom! I'm playing games!!!

Here's my steps:
Mapped Arduino Nano to Atmega pins in schematic
Mapped " ISP to Jytech USBasp programmer I had
Wire up SD card - used R1=22 and R2=47 ohm V-divider from 5V input (3.4V), Photoresistor, Speaker (from old phone)- also used 2N222a bjt (didn't have a hi-freq one - seems to work fine), buttons, LCD, Pot (behind LCD)
Followed instructions from wiki for bootloader
Followed instruction from Arduino website for burning from Arduino IDE - Not sure if I did this right - still haven't loaded a game from SD yet!
Loaded a sketch (basic) and moved curser around to map buttons to Nano correctly - I left a little extra wire on each for this
Played a little Crabator!

P.s. I created image and text files of the mappings but know that I read somewhere on here that Rodot doesn't want to upload his schematics yet, so unless I get his blessing I will hold off for now!

Well done Sir, congratulations!

Schematics have been on the wiki for a while, so you can upload pin mapping if you want, no problem!

Ok cool! I meant the board layout, which I thought you said you didn't want to make it too easy for Chinese manufacturers! (so anything that would make it easier for them would fall into that category..)

Let me know if you don't want it up and I'll take them out of my sig... which is where I'll post the links!

Rodot mean the PCB design.

[treflip]

Right, but anyone can make the board layout with the schematics and circuit software. The pin mappings just make it easer to connect the traces!

[ripper121]

The schematics are already online and public.

Nice work treflip, your schematics are really nice. I love the colored wires. Which program did you use?

I did the same thing with my nano.
Only thing that doesnt work on my nano was the bootloader.
I can read the sd card, load games with the loader sketch, but i cant invoke it when the C button is held on startup.
I was discussing it in this thread:
viewtopic.php?f=7&t=526

Anyway...hope you make the bootloader work on your nano

Hey Albertinjo!

Thanks! I use MSpaint. It does most of what I want, most of the time!

I haven't proven I can write/read to/from SD card yet (just probed it w/ Logic Analyzer a little) but I have the same problem with loading from SD... I'm in the process of recompiling the gamebuino_boot.c file in the gamebuino_boot folder but get this error:

Code:

/bin/sh: -c: line 0: syntax error near unexpected token `('

]

Not sure where it is cuz line 0 isn't found anywhere and ( is a very common character!

nice! Never used a breadboard before, myself.

[treflip]

Thanks! Breadboards are pretty good... I use them for anything temporary... but I guess that's what they're for huh!

I have a power source I made from an old pc power supply. It has like 10 amps at 12v, which is fine for most stuff! and a nice digital multi-meter (DMM), which covers most of the tools I use regularly.
